Yes they can.

Big government can contain its further expansion if the government chooses to. This is up to them. They can either stop getting in our business as much. Stop frivolous spending. Or not. It will be hard for them because they love to be in our business and they love to spend. But they could stop it if they wanted to.

No, Big government can't contain its further expansion

I believe that a big government is hard to govern within itself. The bigger a government is the more debate and unecessary arguments it can bring amongst different political parties. I think that a small and efficient government is way better when it comes to policy matters and economic policy.
